MiguelOh dear! It looks like I am probably mistaken. The reason I had thought there was a "correct" spelled version of the E101 is because I was using vintagecardprices.com's catalog and there is a "Correct spell Mathewson" variation listed. On further inspection, that seems to be the only E101 Set of 50 Mathewson that's listed, so I think I've just fallen victim to an unclear descriptor on the VintageCardPrices site.
My apologies for the trouble, and thanks for the quick responses in setting me straight!
